how to run osmocom-bb with grgsm in usrp b210 to connect openBTS?

by hellowangfang＠gmail.com

I used osmocom-bb and grgsm with usrp b210 to connect openBTS, but failed. The command is "./mobile -c /home/oi/wf/osmocom-bb/doc/examples/mobile/default.cfg","./trxcon -p 5075 " ,"grgsm_trx -p 5075" . When i used “./cell_log -A 1 ”， it could find plmn 1-1 with arfcn 1 which is same with openBTS. DSUM INFO cell_log.c:344 Sync ARFCN 1 (rxlev -105, 1 syncs left) DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:344 Sync ARFCN 1 (rxlev -105, 1 syncs left) DSUM INFO cell_log.c:190 Cell: ARFCN=1 MCC-MNC=001-01 (Test, Test) But when test with sim testcard 1, it failed to find the 1-1 cell. Could anyone give any suggestion about this? Thanks a lot! 6.5.0-25-generic #25~22.04.1-Ubuntu osmocom-bb: commit 0d1ab4c8d2cbe0ba72662d5b466fb6c60cb8b45f (HEAD -> master, origin/master, origin/HEAD) grgsm: https://github.com/bkerler/gr-gsm.git origin/maint-3.10_with_multiarfcn

Hi there, You have to give these things some time. There are some good notes of expected behavior and bytes here: https://osmocom.org/projects/baseband/wiki/CompalRamloader -Craig On July 9, 2024 1:35:27 PM CDT, "حمۆدِيَ M" <jafar.jjjh63(a)gmail.com> wrote: >Hello .
